Eclipse hangs on loading workbench

Try the following:

1. Delete your .eclipse directory in your home directory. Launch eclipse. If that doesn't work,
2. Open eclipse under another user account. If it loads, you know the problem is with your account, not your eclipse installation.
3. If #2 didn't work your workspace might be screwed up. Delete the .metadata folder in your localworkspace (this is what worked for me). It seems that it contains a .LOCK file that if not properly closed, prevents eclipse from starting properly.

startActivityForResult

From your FirstActivity call the SecondActivity using startActivityForresult() method

eg:

Intent i = new Intent(this, SeconActivity.class);
startActivityForResult(i, 1);

In your SecondActivity set the data which you want to return back to FirstActivity, If you don't want to return back don't set any.

eg: In secondActivity if you want to send back data

 Intent returnIntent = new Intent();
 returnIntent.putExtra("result",result);
 setResult(RESULT_OK,returnIntent);     
 finish();

if you don't want to return data

Intent returnIntent = new Intent();
setResult(RESULT_CANCELED, returnIntent);        
finish();

Now in your FirstActivity class write following code for onActivityResult() method

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

if (requestCode == 1) {

     if(resultCode == RESULT_OK){

      String result=data.getStringExtra("result");

}

if (resultCode == RESULT_CANCELED) {

     //Write your code on no result return 

}
}//onAcrivityResult
